Front Immunol 2023; 14:1122352. [PMID: 36875059 PMCID: PMC9981667 DOI: 10.3389/fimmu.2023.1122352] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Accepted: 02/09/2023] [Indexed: 02/19/2023] Open
Abstract
The morbidity and mortality of lung cancer are increasing, seriously threatening human health and life. Non-small cell lung cancer (NSCLC) has an insidious onset and is not easy to be diagnosed in its early stage. Distant metastasis often occurs and the prognosis is poor. Radiotherapy (RT) combined with immunotherapy, especially with immune checkpoint inhibitors (ICIs), has become the focus of research in NSCLC. The efficacy of immunoradiotherapy (iRT) is promising, but further optimization is necessary. DNA methylation has been involved in immune escape and radioresistance, and becomes a game changer in iRT. In this review, we focused on the regulation of DNA methylation on ICIs treatment resistance and radioresistance in NSCLC and elucidated the potential synergistic effects of DNA methyltransferases inhibitors (DNMTis) with iRT. Taken together, we outlined evidence suggesting that a combination of DNMTis, RT, and immunotherapy could be a promising treatment strategy to improve NSCLC outcomes.

Abstract
Pancreatic cancer is one of the leading causes of cancer-related mortality in both developed and developing countries. The incidence of pancreatic cancer in China accounts for about a quater of the global incidence, and the epidemiological characteristics and therapeutic strategies differ due to social, economic, cultural, environmental, and public health factors. Non-domestic guidelines do not reflect the clinicopathologic characteristics and treatment patterns of Chinese patients. Thus, in 2018, the Chinese Society of Clinical Oncology (CSCO) organized a panel of senior experts from all sub-specialties within the field of pancreatic oncology to compile the Chinese guidelines for the diagnosis and treatment of pancreatic cancer. The guidelines were made based on both the Western and Eastern clinical evidence and updated every one or two years. The experts made consensus judgments and classified evidence-based recommendations into various grades according to the regional differences, the accessibility of diagnostic and treatment resources, and health economic indexes in China. Here we present the latest version of the guidelines, which covers the diagnosis, treatment, and follow-up of pancreatic cancer. The guidelines might standardize the diagnosis and treatment of pancreatic cancer in China and will encourage oncologists to design and conduct more clinical trials about pancreatic cancer.

Abstract
INTRODUCTION Gemcitabine is a nucleoside analog and pyrimidine antimetabolite that inhibits RNA synthesis, currently approved for use to treat a variety of cancers, among which ovarian cancers. Gemcitabine is considered relatively safe and it is generally well tolerated, with rarely reported cardiac side effects. CASE REPORT We report a case of gemcitabine induced dilated cardiomyopathy in a 41-year-old woman receiving gemcitabine as second line treatment for platinum-resistant ovarian cancer without pre-existing hypertension or significant cardiac history.Management and Outcome: The patient presented with clinical symptoms and laboratory and imaging results suggestive of congestive cardiac failure, with a left ventricular ejection fraction of 15%. Gemcitabine administration was stopped and Furosemide with ACE-inhibitors and Beta-blocker agents were initiated. At that point the clinical situation improved: symptoms and findings disappeared with gemcitabine cessation. DISCUSSION Our case demonstrated for the first time objective evidence for dilated cardiomyopathy induced by gemcitabine in a young patient with platinum-resistant ovarian cancer without pre-existing significant cardiac history. Although rare, gemcitabine-induced cardiotoxicity should be promptly recognized in order to take appropriate measures to manage it.

Abstract
Radiotherapy is an important modality for treatment of carcinomas; however, radio‐resistance is still a difficult problem. Aberrant epigenetic alterations play an important role in cancer development. Among epigenetic parameters, DNA methylation has arguably attracted the most attention in the radio‐resistance process. To determine the role of DNA methylation in radiation resistance, several studies were conducted. We summarized previous studies on the role of DNA methylation in radiotherapy. We observed this significant role of DNA methylation in genes related to DNA repair, cell proliferation, cell cycle process, and re‐oxygenation. Furtherly, we also conclude the predictive effect of DNA methylation on tumor radio‐sensitivity and the using of DNA methyltransferase inhibitors in clinical practice. DNA methylation plays a pivotal role in the radio‐sensitivity of tumor radio‐therapy. While hyper‐methylation or hypo‐methylation of genes is related to gene functions.

Abstract
Gemcitabine is not considered a cardiotoxic agent generally; so far only very few case reports have been reported in the literature on different aspects of cardiac side effects. Here we report a case series of 3 patients who developed congestive cardiac failure, when treated with gemcitabine monotherapy in the adjuvant setting for pancreatic cancers. Adjuvant chemotherapy with gemcitabine has been the standard of care for pancreatic cancer patients after successful surgery since the results of the CONKO-001 and ESPAC3 study were published. Gemcitabine was administered on days 1, 8, and 15 of a 28-day cycle at 1,000 mg/m2. All 3 patients developed symptoms suggestive of cardiac failure with a drop in ejection fraction on echocardiography, and responded to conservative treatment for heart failure after withdrawal of gemcitabine therapy. Early withdrawal of gemcitabine chemotherapy is recommended in addition to a need for studies required to evaluate the mechanism of cardiotoxicity. As per available literature, patients with diabetes and having received a total dose greater than 15,000 mg/m2 are generally at a higher risk and require close surveillance.

Improved Survival in Patients with Resected Pancreatic Carcinoma Using Postoperative Intensity-Modulated Radiotherapy and Regional Intra-Arterial Infusion Chemotherapy. Med Sci Monit 2017; 23:2315-2323. [PMID: 28512284 PMCID: PMC5443358 DOI: 10.12659/msm.904393] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2017] [Accepted: 04/25/2017] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND We assessed the role of adjuvant intensity-modulated radiotherapy (IMRT) in combination with chemotherapy for pancreatic carcinomas after curative resection and identified prognostic factors related to pancreatic carcinoma after multidisciplinary treatment strategies. MATERIAL AND METHODS Pancreatic carcinoma patients (n=61) who received adjuvant radiotherapy after resection (median dose, 50.4 Gy) between 2010 and 2016 were retrospectively identified. Sixty patients received chemotherapy, including concurrent chemoradiotherapy (CCRT), systemic chemotherapy, and regional intra-arterial infusion chemotherapy (RIAC). The Kaplan-Meier method was used to measure the 3-year overall survival (OS) and disease-free survival (DFS) rates. Log-rank univariate analysis and multivariate Cox regression model analysis were used to identify prognostic factors. RESULTS Median follow-up time was 25.5 (range, 4.9-59.7) months. The 3-year OS and DFS rates were 31.0% and 16.1%, respectively. The median OS and DFS were 27.4 and 16.7 months, respectively. Multivariate analysis indicated that independent favorable predictors for OS were CCRT (p=0.039) and postoperative RIAC (p=0.044). Moreover, postoperative RIAC (p=0.027), and pre-radiotherapy CA19-9 ≤37 U/mL (p=0.0080) were independent favorable predictors for DFS. The combination of radiotherapy and chemotherapy was tolerated well by the patients, and no treatment-related death occurred. CONCLUSIONS Combined IMRT and adjuvant chemotherapy appeared safe and effective for pancreatic carcinoma. CCRT was associated with improved survival with acceptable toxicity. We propose that radiotherapy could be a part of postoperative treatment, but it should be administered concurrently with chemotherapy. Adding RIAC was associated with improved OS and DFS and it could be integrated into the postoperative treatment regimen.

Pancreatic Cancer: 80 Years of Surgery-Percentage and Repetitions. HPB SURGERY : A WORLD JOURNAL OF HEPATIC, PANCREATIC AND BILIARY SURGERY 2016; 2016:6839687. [PMID: 27847403 PMCID: PMC5099466 DOI: 10.1155/2016/6839687] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/05/2016] [Accepted: 06/01/2016] [Indexed: 12/18/2022]
Abstract
Objective. The incidence of pancreatic cancer is estimated to be 48,960 in 2015 in the US and projected to become the second and third leading causes of cancer-related deaths by 2030. The mean costs in 2015 may be assumed to be $79,800 per patient and for each resection $164,100. Attempt is made to evaluate the results over the last 80 years, the number of survivors, and the overall survival percentage. Methods. Altogether 1230 papers have been found which deal with resections and reveal survival information. Only 621 of these report 5-year survivors. Reservation about surgery was first expressed in 1964 and five-year survival of nonresected survivors is well documented. Results. The survival percentage depends not only on the number of survivors but also on the subset from which it is calculated. Since the 1980s the papers have mainly reported the number of resections and survival as actuarial percentages, with or without the actual number of survivors being reported. The actuarial percentage is on average 2.75 higher. Detailed information on the original group (TN), number of resections, and actual number of survivors is reported in only 10.6% of the papers. Repetition occurs when the patients from a certain year are reported several times from the same institution or include survivors from many institutions or countries. Each 5-year survivor may be reported several times. Conclusion. Assuming a 10% resection rate and correcting for repetitions and the life table percentage the overall actual survival rate is hardly more than 0.3%.

Abstract
This population-based study evaluated the survival impact of postoperative radiotherapy (PORT) in left-sided pancreatic cancer. The Surveillance, Epidemiology, and End Results (SEER) database was used to identify patients with surgically resected left-sided pancreatic adenocarcinoma from 2004 to 2010. Propensity score matching was conducted to compare PORT and non-PORT groups. A total of 445 patients were identified, and PORT was performed in 180 (40 %) patients. In the unmatched population, there were no significant differences in overall survival (OS) (P = 0.197) and cause-specific survival (CSS) (P = 0.379) between the PORT and non-PORT groups. After propensity score matching, the patients treated with PORT had longer median OS (P = 0.012) and CSS (P = 0.039) than the non-PORT group. In propensity-adjusted multivariate analysis, non-receipt of PORT was a poor prognostic factor in OS (hazard ratio [HR] 1.39, 95 % confidence interval [CI] 1.08-1.79), and CSS (HR 1.31, 95 % CI 1.01-1.71). The log odds of positive lymph nodes (LOODS) (≥-0.73) was also associated with worse OS (P = 0.003) and CSS (P = 0.001). In left-sided pancreatic cancer, considering the addition of PORT is a reasonable option as in pancreatic head cancer. The LOODS was suggested as a strong predictive indicator of the patients' prognoses.

Abstract
BACKGROUND Eribulin mesylate is a synthetic microtubule inhibitor that showed cytotoxic synergy in combination with gemcitabine preclinically. This combination was assessed in a Phase I dose-finding trial in patients diagnosed with advanced solid tumours who had received up to two prior chemotherapy regimens for metastatic disease (CP cohort). METHODS Dose escalation was performed in a 3+3 design to identify the recommended phase II dose (RP2D). Two additional expansion cohorts in women with gynaecologic cancers at the RP2D (G), and further dose escalation of metastatic chemotherapy-naive patients (CN), were evaluated. RESULTS 45 patients were treated: 21 (CP), 10 (G) and 14 (CN). The initial combination of eribulin and gemcitabine was administered on days 1, 8, and 15 of a 28-day cycle; however, due to 2 out of 6 dose-limiting haematological toxicities at the first dose level, a reduced dose-intense schedule was assessed. The RP2D was defined at 1.0 mg m(-2) eribulin and 1000 mg m(-2) gemcitabine day 1 and 8 q3 weeks. No other significant toxicities were observed in the G expansion cohort. Neutropenia prevented further dose escalation in the CN cohort. Objective responses were seen in all three cohorts - 2/21 (CP), 1/10 (G) and 2/14 (CN). CONCLUSIONS The combination of eribulin and gemcitabine was well tolerated at the RP2D.

Simultaneous delivery of cytotoxic and biologic therapeutics using nanophotoactivatable liposomes enhances treatment efficacy in a mouse model of pancreatic cancer. NANOMEDICINE-NANOTECHNOLOGY BIOLOGY AND MEDICINE 2015; 12:223-34. [PMID: 26390832 DOI: 10.1016/j.nano.2015.08.007] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/16/2015] [Revised: 08/28/2015] [Accepted: 08/28/2015] [Indexed: 01/18/2023]
Abstract
A lack of intracellular delivery systems has limited the use of biologics such as monoclonal antibodies (mAb) that abrogate molecular signaling pathways activated to promote escape from cancer treatment. We hypothesized that intracellular co-delivery of the photocytotoxic chromophore benzoporphyrin derivative monoacid A (BPD) and the anti-VEGF mAb bevacizumab in a nanophotoactivatable liposome (nanoPAL) might enhance the efficacy of photodynamic therapy (PDT) combined with suppression of VEGF-mediated signaling pathways. As a proof-of-concept we found that nanoPAL-PDT induced enhanced extra- and intracellular bevacizumab delivery and enhanced acute cytotoxicity in vitro. In an in vivo subcutaneous mouse model of pancreatic ductal adenocarcinoma, nanoPAL-PDT achieved significantly enhanced tumor reduction. We attribute this to the optimal incorporation of insoluble BPD into the lipid bilayer, enhancing photocytotoxicity, and the simultaneous spatiotemporal delivery of bevacizumab, ensuring efficient neutralization of the rapid but transient burst of VEGF following PDT. From the Clinical Editor: Most patients with pancreatic ductal adenocarcinoma (PDAC) by the time present the disease it is very advanced, which unavoidably translates to poor survival. For these patients, use of traditional chemotherapy often becomes ineffective due to tumor resistance to drugs. Photodynamic therapy (PDT) can be an effective modality against chemo-resistant cancers. In this article, the authors investigated the co-delivery of a photocytotoxic agent and anti-VEGF mAb using liposomes. This combination was shown to results in enhanced tumor killing. This method should be applicable to other combination of treatments.

Abstract
OBJECTIVES Adjuvant therapy after surgical resection is the current standard for pancreatic adenocarcinoma; however, the role of chemoradiotherapy (CRT) remains unclear. This study was conducted to compare the efficacy outcomes with adjuvant gemcitabine and gemcitabine-based CRT (CT-CRT) versus gemcitabine chemotherapy (CT) alone after pancreaticoduodenectomy. METHODS Among 165 patients who underwent surgical resection for pancreatic cancer at Indiana University Medical Center between 2004 and 2008, we retrospectively identified 53 consecutive patients who received adjuvant therapy (CT-CRT=34 patients; CT=19 patients) and had adequate follow-up medical records. The median follow-up was 19.1 months. Median disease-free (DFS) and overall survival (OS) were determined using Kaplan-Meier method, and a Cox-regression model was used to compare survival outcomes after adjusting for age, status of resection margins, and lymph node involvement. RESULTS The OS for the CT-CRT group was significantly higher compared with the CT group (median, 20.4 vs. 16.6 mo; hazard ratio, 2.42; 95% CI, 1.17-5.01). The median DFS for the CT-CRT group was 13.7 versus 11.1 months for the CT group (hazard ratio, 2.88; 95% CI, 1.37-6.06). On subgroup analyses, significantly superior OS and DFS were observed among patients younger than 65 years, T3/T4 tumor stage, negative resection margins, and positive lymph node involvement. CONCLUSION Gemcitabine plus gemcitabine-based CRT compared with gemcitabine alone leads to superior DFS and OS for patients with resected pancreatic cancer.

Abstract
Introduction Newly developed antineoplastic drugs have resulted in improvements in morbidity and mortality from many forms of cancers. However, some of these new chemotherapeutic agents have potentially lethal side effects, which are now being exposed with their widespread use. Gemcitabine is a nucleoside analog, which is a commonly used agent for various solid organ malignancies. Phase 1 and 2 trials with gemcitabine did not show significant risk for cardiotoxicity; however, with its widespread clinical use over the last decade, a few cases of cardiotoxicity related to gemcitabine use have been reported. Cardiomyopathy after the use of gemcitabine monotherapy is extremely rare; and only one such case has been reported in detail previously. Case presentation We report a case of a 56-year-old African American man with pancreatic cancer who presented with signs and symptoms of congestive heart failure after being treated with gemcitabine for two cycles (six doses). A two-dimensional echocardiography showed left ventricular ejection fraction of 15 to 20 percent with global hypokinesia. With the absence of significant risk factors for coronary artery disease and a strong temporal relationship with the initiation of chemotherapy, it was concluded that our patient’s cardiomyopathy was related to the use of gemcitabine. Gemcitabine was discontinued and our patient responded well to standard heart failure therapy. Two months later, a repeat echocardiogram showed significant improvements in left ventricular systolic function. Conclusions Gemcitabine should be considered as a potential cause of cardiomyopathy in patients receiving chemotherapy with this drug. We need further studies to look into potential mechanisms and treatments of gemcitabine-induced cardiac dysfunction.
